to stormwater infrastructure to transport water away from the urban environment. one approach was to carry waste and stormwater through the same pipe. this combined system was less expensive than building two individual pipe networks. and stormwater was seen as a way to flush out the sewers. through the 19th century, the combined system was considered state-of-the-art throughout the world, and is still in use in many cities today. but cities constructed these systems before treatment was the standard. and even today's largest treatment plant doesn't have the capacity to treat the sudden volumes of water rushing through a combined system during rain. the plant is overloaded, and the excess rainwater, mixed with untreated raw sewage, is diverted straight into local waterways, creating a combined sewer overflow, or cso. there are over 700 communities in the united states with combined sewer systems. the other approach was to separate wastewater from stormwater, using two pipe networks. this separate system simply carries the stormwater away from the city. but even separate systems pollute the water
